Raman spectroscopy and Raman microscopy are high efficient method for identification. Combined with FT-IR technics you can have full range of material characterization. You can have all the information about the chemical composition, structure and element contating by any or minimal sample preparation. Thermo Scientific DXR series gives you high quality spectra and images which are very usefull for scientists and control labs. Different modifications, accessories and softwares give you a lot of possibilites for applications with different matrixes and characterisctics of interest.
